There are many parasites that affect the hormones of their infected that live in symbiosis with their hosts. For example, cats have parasites in their feces that make their prey less afraid of them when infected. True mind-control is not really plausible scientifically because you'd need to intercept trillions of synapse connections and manipulate each one in precise patterns without accidentally shutting down vital systems killing the host, but changing a person's biochemistry to include artificial emotions such as love, compasion, fear, peace, forgetfulness, etc. could all be done, because that is just a matter of attacking and stimulating glands.
I would suggest that the Vampire have a number of parasites with unique effects on people's hormone balance that they could introduce at will for whatever desired effect they want. The effects would not be immediate, but a Vampire could stalk a victim for days, first infecting them, then come back next week to exploit the hormone shift. Theoretically, the hormone shift could be keyed to make the victim highly compliant to the vampire in response to his specific pheromones the same way women become more attracted to men with a lot of testosterone when they are ovulating.
Alternately, there is the option of mind-altering drugs (like a natural truth serum, opioids, hallucinogens, etc.) which would give much faster results, but for much shorter periods of time.
Pheromones themselves could also play a part as hyperion4 suggested, but those would be limited to how responsive your victim already is to them. So if you think about how much extra control a musk body spray gives you in a situation, that is about the limit of that advantage.
If you mix the ideas, then pheromones could be used to get close to your victim, then a bite could be used to introduce the natural drugs to quickly bring a victim into a highly compliant state. Then if you need a more lasting control over your victim, you make them drink your blood to "thrawl" them into a more permanent state of compliance with body altering parasites.
As for where this virus might come from, a theoretical distant cousin of Baculoviridae may be what you are looking for. In nature it only affects arthropods, but it has several of the qualities you are looking for. It increases appetite which could perhaps compel a person to vampirism if the cravings are specific enough as well as boost metabolism which could make it's host faster stronger and heal more quickly, it is typically fatal, and it has multiple stages that it goes through when it infects a host which could mean that is has an early stage where it makes the host compliant to suggestion in response to a mature host's pheromones, but as it takes hold of the victim's body and finished causing the mutations that make the vampire (through gene replacement), it would either die from the infection in a manner as unpleasant as a flesh-eating virus or it would survive to become a mature vampire.
While this would be a big leap of faith for evolution, as a bio-engineered weapon, all the elements you need are right there in nature to be exploited by someone smart/terrible enough to really work at it.
There is a whole Wikipedia page about such parasites. Taking a look there and doing some follow-up research should help you a lot.
