If you like Complete Scoundrel I say run with it. I like the flavour of a Malconvoker. It would allow you to be the guy that spams the enemy with critters. You don't have to worry about buffing your fellow players as if you like you can buff the creatures you summon. And hey, you get demons. Since you don't like wizards, try a cleric of Boccob as the entry class, with the Magic domain for wand/staff/scroll use and the Trickery domain to keep the Bluff skill at max (luckily the class gives you skill focus: bluff). The cleric class gives you the other prerequisites for the prestige class (languages, knowledge (planes). You can take the two feats you need at 1st and 3rd if you don't want to be human. I would assume a race with darkvision would be helpful with Mr. Vampire around.
At 10th level you could be a 5th Cleric/5th Malconvoker. You cast as a 9th level cleric, but your summoned fiends start "pre-buffed" with extra hit points and weapon damage, plus you get an extra one for each Summon Monster spell that you cast (kinda like a 2 for 1 when you cast Summon Monster V). Also, the right fiends can see just fine in any magical darkness your friend casts around him.
You might get a bad reputation, but since you are travelling with a vampire I assume you don't care much about that at this point.
Alternatively, take a cleric at 10th of Wee Jas and just rebuke your vampire friend and make him do whatever you want for the rest of the game.
