The blessing over matzah is the same as that over any other bread. Say this blessing before eating matzah.
בָּרוּךְ אַתָּה, יְיָ אֱלֹהֵינוּ, מֶלֶךְ הָעוֹלָם,
הַמּוֹצִיא לֶחֶם מִן הָאָרֶץ.
Baruch atah, Adonai Eloheinu,
Melech haolam,
haMotzi lechem min haaretz.
Blessed are You, Adonai our God, Sovereign of all, who brings forth bread from the earth.
At a Passover seder we say an additional blessing before eating the matzah.
בָּרוּךְ אַתָּה, יְיָ אֱלֹהֵינוּ, מֶלֶךְ הָעוֹלָם,
אֲשֶׁר קִדְּשָׁנוּ, בְּמִצְוֹתָיו וְצוָּנוּ, עַל אֲכִילַת מַצָּה.
Baruch atah, Adonai Eloheinu, Melech haolam, asher kid'shanu b'mitzvotav, v'tzivanu al achilat matzah.
Blessed are You, Adonai our God, Sovereign of all, who hallows us with mitzvot, commanding us regarding the eating of Matzah.
