I'm pretty certain Isiah is a common alternate spelling of Isaiah, and should be pronounced exactly the same? So it should be the same in Japanese katakana as Isaiah would be.
I have a Bible written in Japanese. As FelliVox said, Isaiah is written イザヤ in Japanese. The Book of Isaiah is イザヤ書 (Izaya-sho), and "Prophet Isaiah" is 預言者イザヤ (Yogensha Izaya). ^^
