Narrative:
ZHU cleared us direct to nepta intersection. The first officer turned and we began to proceed to nepta. ZHU called us some time later and told us to turn right to a heading of 170 degrees. He said that we had proceeded beyond nepta and to reintercept the airway and gave us a frequency change to ZJX. I asked ZJX if we had created a problem for anyone and the controller stated that he had seen our deviation and had advised the military of our violating their warning area. After ZHU cleared us direct to nepta we did not engage the auxiliary/navigation mode of the autoplt. This was due to our talking amongst ourselves in the cockpit and not paying attention to the task at hand. We also did 1 step less than what was required by not engaging the auxiliary/navigation mode of the autoplt.
