I am in no way a certified golf teaching pro, but I'll tell you what my teacher had me do. First, we made sure that my grip was strengthened like the Ben Hogan books suggest. Then, we worked on making sure that the shaft was pointed at the hole and parallel to the ground while the clubface was 90degrees open 1/4 of the way through my takeaway. We just started swinging from there, making sure that the lower body didn't move and that the club was brushing the mat just past the impact point. Once that was reliable, we started hitting balls like that. Once that was sound, we added a little more distance on the backswing and slowly added some hip rotation.

Having said all of that, you'll be better off going to see a teaching pro. 40 bucks for a 1/2 hour lesson will really change your game for the better.
