Does anyone knows of a good prayer book?

We started a bible study with my kids and husband. Every night we read 2 chapter and we ask each other questions of what we read and how we understand it. I am open to ideas or books that can help us out. Also we pray before we let them go to bed. We are new to this and would like some guidance. We are currently looking for a church. So I have no idea how to do this right.

Thank you for your advice
