I teach my kids to live life well, be nice to other folks, and be happy. If they get those things right, the rest will fall into place. Of course, as an atheist that fits my (lack of) "religious" views perfectly. I think that what you want to teach them will always be overshadowed by what they learn from watching what you do. If you live your religion well they will pick up on it without any extra effort from you. If you don't really follow your religion and just attempt to make your kids follow it, it won't work.
