wherever you hunt them, research what they've been dining on and base your tactics on that.
Been eating chickens, well hang out by the chickens. Goats, imitate distressed kids. Pigs, same thing.
last year or so, I've had better luck laying in wait at the site of their victims than with calling. They follow trails, hedges, fences, rows of crops, and so on. Its easy enough to find how they travel at night.
Best calling method is coyote sounds, but nothing is ever set in stone with them. I've had them wander straight at me with the wind in my their before, which is counter intuitive in coyote behaviour.
Two more tips
1. If you make your own call lanyard, you may pee on it if its too long.
2. Beware the coyote shaped bushes, stumps and rocks.
