Bad postdoctoral advisor, help needed
It sounds like you are having a hard time making the transition from knowledge consumer to knowledge producer. While it is nice to get additional training as a post-doc, by this time you are the expert and you should be driving your research efforts, not your post-doc supervisor. In fact, you may be on the post-doc precisely because your area of expertise is different than that of your supervisor, and he may be looking at you wondering why you aren't proposing research.

The fix is simple but not easy:


Change your mindset to that of an independent researcher. You are an expert and a professional now, and your research is your responsibility.
Take the work from your dissertation, and develop a plan to expand on and/or publish that research.
Discuss integrating your research into the remaining post-doc.


Like I said, simple but not easy. There are many people who may be able to help you in this, including your PhD advisor and your post-doc supervisor. The process is going to be highly individualized, but is critical to your progress as an independent scholar, so do not delay.
