Well, the standard lich applies to clerics as well - SRD: A lich is an undead spellcaster, usually a wizard or sorcerer but sometimes a cleric or other spellcaster, who has used its magical powers to unnaturally extend its life.
Though there was also a specific lich for clerics of Bane in Monsters of Faerun - I think it was called, with great originality, a Banelich.
