There are no officially recognized English translations.
If you like the KJV style, there is an online translation of the Orthodox Old Testament in the style of the KJV:

I would say the KJV's New Testament has no serious problems for Orthodox, so if you like that version the best stick with it.
For printed Bibles, I would say the Orthodox Study Bible (with both testaments), while far from perfect, is probably our best option overall at the moment.
