I don't know the nature of your group, but I've had some great success with a range of students using Noisy Stories (just search and you can find a whole book of them for sale, or you can make your own to target certain sounds or question constructs), and they can be good for phonological awareness. I also use the Matt and Molly curriculum. It can be easily adapted, and works on a variety of receptive and expressive language skills. It's specifically designed for kids on the spectrum, but even the typically developing peers in the preschool love it. I do a story for two weeks (two circle times), and put up the pictures in the classroom and have the props available, and you get kids acting out stories and using all kinds of practiced language in appropriate play. They're great!
