I too think modern vampires are overpowered.
I think a vampire's primary powers should be mental or intangible - they should be able to fascinate or mentally dazzle people with weaker minds [particularly those of the gender opposite that of that vampire]; they should be able to inspire fear or madness. They should be physically strong enough to overpower a victim, but they should not be the Incredible Hulk. And they should be able to transform into bats or some other "familiar" animal. But that's it.
