The sticking point here is phonemic and non-phonemic sequences, which
doesn't have a clear solution. On the one hand, I think you'd be very
justified in going with the phonetic equivalent, and writing your "I"
as "ay". On the other hand, consider the relative frequency of V+y

ay - very common as "long i"
ey - very common as "long a"
oy - somewhat common, but spelled as oy or oi
uy - very rare, occurs sometimes in borrowings

I don't believe that other V+y sequences occur at all. What this
demonstrates is that English doesn't, in general, allow any vowel to
be followed by /y/, but rather has a pretty limited set of diphthongs
that are arguably phonemic. So the choice is up to you. If you want a
completely phonetic spelling (which I believe was your original
intent), then V+y and V+w sequences should be spelled as diphthongs.
If you want a phonemic spelling, then write them as single symbols.

The y+V sequences, on the other hand, are clearly a sequence of two
phonemes. Any vowel can occur after /y/ (I quickly came up with yeast,
yay, yes, yak, yon, young, yore, you), and they don't begin with a
glottal stop (indicating that the /y/ is being treated as a
consonant). There is no other reason to treat them as monophonemic.
