Negative form Future Tense is very easy! Use "-me" and "-ma" negativeness suffixes for that:

If last vowel of verb stem is one of "a, ı, o, u" then put "-ma"

If last vowel of verb stem is one of "e, i, ö, ü" then put "-me"

We put "y" between negativeness suffix and Future Tense suffixes; likewise you see:

Gör + me + y + ecek: He/she/it won´t see.

Kapat + ma + y + acak: He/she/it won´t close.

Gitmeyeceğim: I won´t go.

Oturmayacaksın: You won´t sit.

Görmeyeceğiz: We won´t see.

Yazmayaksın: You won´t write.
