This seems like an experiment that most easily done with a willing volunteer. Not you, of course. You need to be a human for that sweet, sweet vengeance because becoming a regenerating, flying creature of the night with enhanced speed, strength, and teeth is really just out of the question. (Because it's so much more satisfying to see the look on their smug superior vampire face when they see they got killed by a puny human, that's why!)
So your best option is to carefully (very carefully!) keep track of these things and try and guess their eating habits. Not to stop them, of course, but because their definitely have to be vampires which are sloppy eaters, and instead of leaving behind a corpse, leave behind a almost-dead vampire. All you have to do is find one of these poor unfortunate souls and rescue them, taking them into your lair. Explain to them that their life has been ruined by vampires, do your best to really get their revenge juices flowing like yours, and then have them undertake a battery of experiments (not designed to be lethal, of course) to see what works and what doesn't.
