I'm on this kind of Buddhism, there's books on it over at /omg/ 
For Mahakala practice, you have to get empowerment from a guru, since he's a wrathful tantric deity.
If you're sincere about it, I can point you to Mahakala empowerment videos that can be followed along. But you should know that Mahakala practice is serious shit, you have to make it a daily commitment for the rest of your life. Still interested?

Mahakala has a self empowerment ritual? I was under the impression there was only one Gelug deity with self empowerment, and also the Shaivite Dakshinamurti
