get a hand call, camo up best you can, (hands and face important) if you can, get shooting stix, and put your back to a tree with a nice vantage of the area you think the yotes might come in from. my favorite hand call is a Circe long/med range rabbit call, and a carlton med size open reed.. just get crazy with the call, manipulating it to make all kinds of crazy sounds, blast that thing for 20 seconds and then wait, then repeat every other minute or so.
get the video, by Randy anderson, titled, "calling all dogs III" it will teach you all you need. especially as to the body language of the dog., learning that will help u decide if your going to take a poke at it at 200 yards, or coax him in and blast him at 10. good luck.
