There are different conventions for writing Hebrew prayers/blessings.... Yod-Yod (יְיָ) is one "circumlocution" for the Divine Name that is traditionally used in many prayer books. For example:
בָּרוּךְ אַתָּה יְיָ אֱלֹהֵֽנוּ מֶֽלֶךְ הָעוֹלָם, הַמֵּכִין מִצְעֲדֵי גָֽבֶר
Praised to You, Adonai our God, Sovereign of the universe,
who strengthens our steps.
