Not sure if you kit has the right feathers, but soft hackles are flies I find easy to tie and are quite effective.
I second the pheasant tail and hare's ear nymphs. Caddis larve are also pretty easy to tie. Unfortunately, I've never caught much on caddis larve in the smokeys though.
Adams dry flies are pretty easy if you leave off the wings (guess it's not really an Adams then but it works and is a very effective fly in the mountains. Post some photos of your flies. I've found the folks on the LRO forum very supportive and suggestions are offered in a spirit of helping and encouragement instead of tearing down what you've done.
Hope this helps.
