ask students general questions about them. Are you a students? Are you intelligent..anything that could be of interest to them. then ask other in the class about other members of the class. Is she your classmate? Is she in the basketball team? Is she good? Kids are very quick at picking up the structure. Put prompts on the board. are you happy? Are you sad? Is the teacher funny? etc.

Or if not bring a poster to the class and ask questions about the poster using yes no questions with the verb to be. and then personalize with the students. Just be dynamic and fun.
