I have loved the book How to Talk So Kids Will Listen, and Listen So Kids Will Talk, by Faber and Mazlish. There is a version especially for teens. The techniques offered are clear, sensible, and respectful. I have gotten wonderful results using this approach with people from age 2.5 up to adult.
It's wonderful that you are noticing the lack of communication and looking for new ways to address it.
