I wrote this simple Python script to analyze the official Scrabble dictionary for words that contain each of the vowels and the letter ‘y’, as you requested:

vowels = set('aeiouy')
with open('TWL06.txt') as file:
    for line in file:
        word = line.strip().lower()
        letters = set(word)
        if vowels <= letters:
            print word

The result is below, sorted alphabetically (156 words).

I did the same thing, but omitted ‘y’. You can see those results (1905 words) here: http://www.michaelfogleman.com/static/files/vowels.txt

Vowel Words FAQ

1. What words use all five vowels?

Unfortunately, most of the words that contain all five vowels are too long to be useful in Scrabble and Words With Friends. They include unequivocally, abstemious, and unquestionably. Eulogia, miaoued, and miauos all use all five vowels and are eminently playable.

2. Are there five or seven vowels?

When it comes to speaking, there could be as many as 20! Even in writing, there could be more than A—E—I—O—U—Y—W. Archaeology, for example, could treat the ae as a single vowel similar to the ä in German. Generally, for crossword games, A—E—I—O—U are considered vowels, and the other letters are considered consonants.

3. What is the longest word that consists of only vowels?

The words with only A—E—I—O—U that are legal to play are all short vowel words of two or three letters. Examples include aa, ae, and eau. If you include Y, then you can get long vowel words like ayaya. You might read about other long vowel words, like a medieval musical term, euouae, but these are not legal in the Official Scrabble Players’ Dictionary.
