As for turning (or as the fancy vampires call it "the embrace"), As far as I can there haven't been many in game turnings so it's hard to tell.
But I think I figured it out:
Drink from a human > nothing happens
Give blood to a human > create a ghoul (human with some minor perks and under your control)
Drain a human, then return some of your own blood > create vampire.

Many vampires have some rituals surounding these things.
Powerful vampires have more uhmm... "trippy" effects on their fledglings.
Aside from the effect of them inheriting some of their ability. (the older the generation of vampire, the better)
Also, vampires are bound to their "sire" and would normally never harm their sire.
This bond can't be broken without at least a few dramatic story lines between the characters.
Or until the sire dismisses their child.
