Baiting and calling are not one of the same. Either bait, which to have good success baiting, it's best to have an endless amount of bait, to freshen the bait on a regular basis, to get the animals to stay in the area, sure you could use a road killed dear to bait with, but if two or threee coyotes show up when you're not there, it'll be gone before you get back. So you need to be able to freshen a bait pile. And is baiting legal in your area?
Calling doens't require the smell of something dying. On the contrary, it's best to keep the area that you are calling odor free, mainly human odor free. Some guys use a decoy, it's also NOT necassary. Learn how to use a hand call, go into the area, call it, and if nothing shows up, move on after 15 upto 30 minutes to a new area. The distress sound is all the bait you need!!
