I've mostly just used google translate to change my own materials into Spanish. The trick is to over simplify the English and grammar you use. I write the English as if I'm talking to my 4th grader. Be terse and to the point using basic words. Then you should check that the Spanish or whatever language translate back to English. If that translation doesn't come back, then change your English word choice and try again.
