I have never done it but would imagine you would need an auto tranny with a 4wd tailshaft, patch the hole in the floor for the standard tranny shifter, replace or fab an auto tranny crossmember, buy flexplate to replace flywheel, torque converter, shifter, tranny cooler, and probably have the length of both driveshafts modified. I had thought about it myself with my 83, but its probably a lot easier to buy another truck thats got an automatic. The value difference between the two are not substantial and you could get a different comparable truck for the same price that you would sell yours for and not really have to shell any money out for the conversion. Or spend a couple thousand dollars converting your truck to auto without really increasing the value of it. Just a thought.
