five thousand (5000)
Surprisingly, one thousand is the first number that has an a in it (but it has two o's)
two thousand has two o's
three thousand has two e's
four thousand has two o's and two u's
five thousand is just right.

Incidentally one thousand five (1005) is the smallest with at least one of each vowel.

If you ascribe to what I consider improper wording then
two hundred and six (206) has one of each.
one hundred and six (106) has at least one of each.

If you don't require integers then you can probably get pretty small:
five thousandths (.005) for example.
but you can use millionths or any -illionths since they have two i's
you also can't use negatives (two e's)

The largest possible number may well be ninety thousand (90,000)
and of course there's no limit if you can use vowels more than once.
