For Thanksgiving, here is a portion of psalm 136 and a prayer based on it. You are always free to use the psalms as the base for prayer and make it yours as you go along.
O give thanks to the Lord, for he is good,
for his steadfast love endures forever.
give thanks to the God of gods,
for his steadfast love endures forever.
give thanks to the Lord of lords,
for his steadfast love endures forever;
who alone does great wonders,
for his steadfast love endures forever;
who by understanding made the heavens,
for his steadfast love endures forever;
who spread out the earth on the waters,
for his steadfast love endures forever;
who made the great lights,
for his steadfast love endures forever;
the sun to rule over the day,
for his steadfast love endures forever;
the moon and stars to rule over the night,
for his steadfast love endures forever;
…
It is God who remembered us in our low estate,
for his steadfast love endures forever;
and rescued us from our foes,
for his steadfast love endures forever;
who gives food to all flesh,
for his steadfast love endures forever.
O give thanks to the God of heaven,
for his steadfast love endures forever.
-Psalm 136:1-9, 23-26
