The Dragon Priests aren't liches, they're just powerful undead mages. If I recall correctly, they sustain themselves by leeching life energy from the Draugr retinues that were buried with them. However, Hevnoraak I believe also achieved lichdom, by separating his soul from his body using his blood as a medium.
