Your strategy won't change much from sw to pw, you just have a little difference in loft to deal with, so the ballflight changes a bit. Off of a bare lie, you don't want to use a lot of bounce. So you need to be a bit steeper and use the leading edge. Set up with more weight on your lead side and try to keep it there throughout the swing. Finish lower and feel like you are knocking it down, keeping the trajectory low. The alignment of the body should be square to the target line.
