For all intents and purposes female White Court Vampires are the Succubi of the Dresdenverse. But if you're going for a more traditional take on them, use the WCV as a base and expand from there. Incite Emotion and it's upgrades is an obvious choice. Some kind of power where they can get into your dreams and seduce you (thus dealing mental stress) wouldn't be hard to design.
Other than that the standard stable of monster powers could apply. glamour, wings, claws, ritual, channeling, inhuman speed, strength, toughness, ect.
