While the name will not translate directly, you can use the katakana alphabet to write the name out. If the name is pronounced as I imagine it is (hey-lee), the romanized Japanese would be "Heiri" (characters he, i, and ri).
Names should be said the same no matter what language.
However, Japanese doesn't really have the "l" sound. The closest a native Japanese speaker is likely to be able to get to "Hailey" using syllables common in Japanese is "ha-re".

Hailey written in Japanese is ヘイリー (Heirii). It's pronounced very similarly to the original name, but obviously an 'r' is used instead of an 'l' as the Japanese don't use this sound.
