if they are not in breeding condition now, if they don't lay in the next week or so, condition them. raise the temp to 82-84f, big(>20%) water change every couple of days, and feed them alot of good stuff. like freeze dried shrimp, earthworms, feeders, black worms, and high quality pellets like cichlid gold. once you've noticed a weight gain, 2-3 weeks probably, they should have leyed eggs by now. for the most part, most cichlids have been shown to breed when they have the opportunity, clean water, 80 degrees, lots of good food, king and queen of the tank, they should breed.
those are really the points you should focus on.
be ready to seperate the female, if she is not ready and the male is, always, he may beat her to death. another tank or a well secured divider should work.
good luck.
