What I usually do is combine random words together, sometimes even three. I made the name Zentinach, the name for a birdlike race, from detergent, soap, and something else I cant remember. I was reading a science book in school. I first got the word Dentinach, then replaced the 'D' with a 'Z'. Just combine random words till it sounds right, it gets boring and repetitive, but is worth it.
