Forward-facing eyes with round pupils, probably not much bigger than a human's, if at all.
Your creatures are predators that seemingly rely a fair bit on vision, therefore, the best configuration relative to the skull would be a more forward facing one, as it allows a wider range of binocular vision, making them better at perceiving depth. As for the pupil shape, let's look at a very useful chart:
AS explained in it, your creature's best pick seem to be round pupils, as, being a predator, they seem to live in conditions much like those of a human, bear or large feline, meaning that they would likely benefit most from the classic round pupils.
Eye size is where things can get funky. For example: some eagles, despite having much smaller skulls, have eyes nearly as big as a human's, since they need their vision to be top notch, and the bigger your eyes, the more space for light-detecting cells you have (for example: in the modern day T-rexes are assumed to having had pretty powerful eyesight, especially since they had eyes about the size of an orange).
If your creature relies mostly on its vision, it might have eyes bigger than an average 6f tall human's, but if it relies more on smell, hearing or both, then human sized might be more than enough (especially if their eyes are more anatomically similar to a bird of prey's, as that'd mean they'd have no problem spotting things from afar, be it their prey from over a mile away or an ant from the top of a 10-story building).
