I teach a conversation class for adult students and we use a book titled Compelling Conversations. It has proven to be a great resource and works well with our class objectives. It costs $20.00 U.S. but is well worth it in my opinion. You can also download some free sample chapters and try them out with your students before you buy.

You may also want to take a look at the Heads Up English website. All the material on the website is free to download. We use the speaking lessons in some of our classes and they have worked great! It�s broken down into four different skill levels, which makes it easy to find something that will match your student�s ability and interests. Good luck!
