Because my tastes in Iranian music run to the strictly classical, my recommendations for dance music are limited. The ones I have listed below I like because they use all acoustic, traditional instruments, not synthesizer, drum machine, etc.
In addition to these recordings, you can also find short dance pieces at the ends of classical music performances, so if you find any classical music recordings, you will find music pieces to dance to. Be sure you use the piece at the end of the performance, in a syncopated 6/8 called reng, not an even 6/8 with a lot of individual improvisations on it. This latter is called chehar mezrab; it is the instrumental soloist's opportunity to shine, and only ignorant people dance to it.
