Various Different Layouts

One on of my websites, I would like a different adsense layout for different types of posts… for example, if it is a post with a long “list,” I’d like there to be 2 ads that appear in between elements of the list. If it is a recipe post, I’d like an ad between the ingredients and the directions. And if it is “regular” post, I’d like an ad to be placed every 200 words (after the next paragraph split). How would I go about setting up these various layouts and assigning them to various posts?

Thanks for your help!
