To help keep mine from drying out - and to grab a bit more smoke, I think - I lightly coat the chicken with mustard right before smoking at ~225 until IT of 165 (or just shy; I then wrap 'em in foil and towel for a little while, until I am ready to do anything more). Outer surface ends up dry to the touch but the meat itself is plenty juicy, and any taste of the mustard ends up being extremely subtle. Doesn't take very long, so I sometimes smoke it alongside some sausage.
Typically, I chop the finished bird up, roughly, and use it in Greek wraps (red onion, feta, tomato, lettuce, tzatziki, olive, etc.), nachos, salads, gumbo, pasta, or just build up some grain base (rice, couscous, etc.). Otherwise, slice it and plate it, and/or build a sandwich around it. Very versatile - it is, after all, boneless chicken.
