Things to say as a dom?

My gf wants to be dommed in bed, and I’m usually very dominant with actions.

She calls me daddy and what not. Bit I mostly assert dominance with the way I hold her, pulling her in, deciding on the position etc

We were talking about it recently and she said I could talk more.

She herself is pretty much quiet during sex - just moans and heavy breathing for the most part, but she wants me to talk more, assert dominance through words.

What can I say? During what? Any resources or videos would help,

Thanks .
