I use only hand calls, so I can't help you on the tape recommendation. Any injured rabbit sound should bring them in if they're in the area. Once you find an area where you know there are coyotes (based on scouting - tracks, scat, etc.), you're better than half-way there. If you're a novice to hand calls, try a closed reed like the Circe, then move on Crit'r Calls or Sceery open reeds. Both of these are generally good producers.
