The usual expression would be [Da bo chi] . This means 'May good things happen to you' and is often used as an alternative to 'Goodbye' in Welsh. ---- If you want the literal translation of [May God bless you] that is:
Duw a'ch bendithio
or
Duw a'th bendithio (this form is only when you are speaking to one person who is a close friend).
God bless = Duw a'ch bendithio
Duw a'th fendithio. (May God bless you.) Bendith Duw arnat. (The blessing of God on you.)
Bendith Duw ar fam
Duw a'th fendithio. Bendith Duw arnat.
We say God bless you as 'Isol nang.na patichina'
