Here is a Youtube teaching by Tenzin Wangyal Rinpoche on the Five Elements Practice:
There is a wonderful book explaining the Five Elements Practices, which I can recommend:
HEALING WITH FORM, ENERGY AND LIGHT : THE FIVE ELEMENTS IN TIBETAN SHAMANISM, TANTRA AND DZOGCHEN
Here is a link to Rinpoche’s organisation. He also gives free live webcasts: http://www.ligmincha.org/en/
