Here are a couple of possibilities:
* Ma-kai-la: This is closest to the English pronunciation, using the "ay" sound like in "day" for the "ai" combination.
* Ma-ka-ya: This pronunciation emphasizes the "a" sounds more, using a slightly softer "a" than in English.
Ultimately, it depends on the individual speaker's accent and preference. You could always ask the French person how they would like to pronounce it.
