There is the typical Slap, Pop, and Tap on Bass by Stu Hamm.
Dave LaRue's video also covers some nice ground, and he has a course on
www.musicdojo.com
I would love to hear some cool suggestions too. Maybe some classical music transcribed for bass that would use tapping. That is one of the reasons it was adapted anyways, to immitate the 2 hand playing of a piano.
