Let's head to the Caribbean now, in particular Trinidad. Here we find the shape-shifting, vampiric hag, the Soucouyant.
The Soucouyant by day appears much as she did in life, an ugly, ancient old crone. By night though she removes her skin (much like a Boo-Hag) and turns into a floating ball of fire. Here she flies around looking for small cracks in peoples homes. She resumes human shape, albeit skinless. She sucks blood from their arms and legs, leaving behind blue marks. She then uses this blood for her magic.
In her fireball form, similar to a Will-0-Wisp or Feu Follet, she is powerless to attack save by blood drain. If attacked she will speed away to her skin, which she keep in a motar. To identify the Soucouyant the next morning look for the old woman covered in bruises.
In her human form she can cast spells as a witch. Her true strengths are her magic and her ability to summon lycanthropes, Loogaroo (a type of werewolf).
To prevent her from entering your home you must leave a pile of rice on the ground or at the local crossroads, which she will be compelled to count. If she is still counting rice when the sun rises she will be destroyed. Also if her skin can be found fill the insides with salt. She will not be able to don her skin and die when the sun rises. The skin of a dead Soucouyant is prized by wizards for it's magical effects.
For Pathfinder a Soucouyant is any hag that the vampire template has been applied to.

The Soucouyant can cast spells and use occult powers as if she were a witch of 7th level of the Demonic Tradition.
A loogaroo is local type of werewolf. They are solitary and can change to large wolf like creatures on the command of the Soucouyant.
The blood drain of the Soucouyant does 1 of Constitution damage. She can only do this while the victim is asleep.
A throwback to their hag/fey origins the Soucouyant is vulnerable to damage from "cold" iron weapons, taking an extra +2 to all damage.
