I’m not Jewish but I used to meditate with a friend from Israel and she said this prayer, so I adopted it.

Baruch Atah Adonai, Eloheinu Melech Ha’Olam, Sh’hecheyanu, V’Kiyemanu, V’Higianu LaZman HaZeh.

Translation: Praised are You, the Eternal One our God, Ruler of the Cosmos, who has kept us alive, sustained us, and enabled us to reach this moment.
