You basically want a bird with scales on its entire body.
Let's look at the things you want really quickly:
Birds are still dinosaurs, and before they underwent a number of adaptations in favor of flight, they actually had clawed hands, longer tails and teeth much like the dromeosaurids you mention. Also here's the foot of a cassowary in case you fear that they can't have murder claws in their feet:
Again check. You don't become capable of flight by needing to bask in the sun every time you need a higher metabolic rate. Birds, like mammals, are active, warm blooded creatures.
- have efficient blood transfer, the ability to regulate their body temperature and pump-action lungs.
Check, check and... I do not know what you mean by pump-action lungs, but if by that you mean very efficient lungs with an uni-directional flow that allows for oxygen absorption both while breathing in and while breathing out, birds also have that. The fact birds can fly (a very energy demanding task that requires proper oxigenation of tissues) and that a lung structure like theirs was seemingly present in 2 of the 3 types of vertebrate to ever achieve powered flight (obviously not accounting humans, because by nature standards we're like a speedrunner exploiting glitches to do things they normally shouldn't be able to) is pretty decent evidence that it's very efficient. The fact you can also find bird species in both extremely hot and dry deserts and in arctic regions show that they can definitely keep their own temperature in check.
- a mammal's energy levels and a reptile's ability to go dormant.
This is a bit of a tricky thing. Birds are just as active as mammals and some birds can actually enter a state similar to hibernation, called torpor, in which they reduce their metabolism, causing their body temperature to drop and allowing them to save energy in harsher conditions. It's not a seasonally locked thing and can actually be done whenever they need it (as a matter of fact, hummingbirds do this every night, because otherwise they'd die of starvation by the start of the next day, given their extremely high metabolism). It's not however like active hibernation, not lasting nearly as much for most species, and the ones that do somewhat hibernate only do it when conditions are favorable, sometimes not hibernating at all.
- have scales, being smooth and green.
This is the main deal-breaker here. Birds do have scales, in their feet, but they're certainly not covered in them, and in fact, neither were the majority of dromeosaurids as far as we're aware. Scales are great protection (especially in the case of osteoderms like seen in crocodiles), but feathers, while not equally as great for protecting the bird against impacts, are great for keeping them warm, with their absence being related to warmer environments and larger theropods. In fact, as far as we're aware, synapsids did not have reptile scales, but rather pseudoscales that some had on their bellies (and we lack fossil information about how the rest of their body looked like, but slightly more recent synapsid species seemed to have had smooth, scale-less skin)
As of now, it seems like you want something that's almost exactly like birds, or rather their ancestors, but that never made the transition from scales to feathers. However, since they're not going to fly, it might be a bit more possible (pterosaurs actually had coverings called pycnofibers, hair like structures which likely helped them stay warm and active in order to fly, potentially allowing some of them to survive in very cold regions).
Assuming everything went just right in terms of mutations and that identical pressures would result in identical or at least very similar traits, your synapsids would basically need to follow an evolutionary path extremely similar to that of theropods and birds, all while either keeping their pseudoscales (assuming they were fully covered in them) or by completely loosing them, evolving hair like modern mammals and then converting it into scales throughout this trajectory.
Essentially, your turbovores' skin would probably look like a larger, more fearsome version of a pangolin, potentially also having scales with sharp back edges.
Either that or they'd potentially have a body entirely covered with a light hair covering and scales like what we find in a rat's tail.
Do note though: scales are a very poor thing when it comes to keeping yourself from freezing. If you want them to live in various regions of your world, you'll need them to rely on methods other than hair and feathers to survive in colder regions. If they truly follow the path of mammals, expect turbovores adapted to cold regions to have a thick layer of blubber underneath their skin.
