As @bytebuster said, this could take an expert a book to answer. But in the spirit of constructive collaboration, let me throw in my two cents:
In Theravada, the focus is on escaping from Samsara to Nirvana, mainly through attaining perfect control of your mind, which in day-to-day life manifests as practice of minimalism.
In Mahayana, the focus is on transcending the dichotomy of Nirvana/Samsara, and realizing the Buddha Nature, mainly through deconstructing the ego; in day-to-day life this manifests as practice of altruism and non-attachment.
In Vajrayana, the focus is on liberating the mind from mental and emotional obscurations so that it can fully enjoy the Natural Perfection that does not need to be attained.
