I don't know exactly, but I am sure that french used to have word /fe:D/ (sorry brackets don't work with this windows email client ). So it gave <foi> /fu^a/ (one could say this in not a diphtong, but I believe it is) from /e:/ > /e^i/ (diphtonguization) > /o^i/ (dissimation) > /u^e/ (mutual assimilation) > /u^E/ (influence of the velar /u/) > /u^a/ . The /D/ comes from regular latin intervocalic /d/ (<fides> if I remember well). But <oi> was concurrenced by <ai>, "I was" was <j'estois> or <j'estais> (now <j'étais>), and that should explain the <ai> in english.
