what level are you starting out at?
some random thoughts
a gestalt Vampire Lord could prove interesting
you could have a wight & Vampire army (so 2 spk)
make one of your mind controlled "friends" or cohort a Werewolf, every new werewolf is under his control now you have a were wolf army as well.
Have your vampires take 1 or 2 levels of shadow dancer, hide in plain site and have a low level magical item or spell that gives them bonuses to hide is shadow...this ought to piss off players as seeing inviso at higher level is common place but a maxed out spot skill is not but with 1 maybe 2 of the party.
Have your were wolves take the Feral template, give the wolfy leaders as much warshaper as possible = your werewolf army will be vicious!
ohhh and having a Vamp Lord waste levels in rogue or any non spell casting class is less than efficient so have him charm/recruite/intimidate the local assassins and thieves guild masters so the party will have to save vs death strike from the shadows every once in awhile.
and if you can have one of the bad guys be a psion, get the spell larval flayers (p 91 complete psion) augment it to max you can and have the em already attached, empower it for a little extra umph and you will instantly have 1 or more players with a severely handicapped int if not 0....no save no spell/power resistance its a touch attack unless you augment already attached, then its basically a brain drain all you can eat fiesta.
