A couple of things that I would do:

-research major paths of travel by looking for tracks, poop, etc.
-Pre-range potential shots from your stand. That would help you determine what would be a reasonable/safe shot based on distance, backstop and cartridge. It also saves time when when the action starts.
-Use bait (a bag of dogfood should work but, if you bait, sometimes it takes a few days for the coyotes to hit consistently) or a call/decoy set-up to direct traffic into your hunting area.
-a fox pro call is very effective. It's what I use in the field. Make sure that you pre-program a "hurt coyote" sound to switch to in case the 'yotes start to run. It usually gets them to stop long enough for a shot.
-If these coyotes are bold enough to go into peoples yards, they may respond calls that mimick domestic cats/kittens, domestic dog/puppies, chickens or other animals that might be found close to houses.
