Hi AJ,
great you like to use Laytheme. Very happy to hear :-)
Without having a look at your page it is a bit difficult to help you. Sometimes you need to add a custom CSS code for the mobile. Because some things will not be active in the mobile version.
You can do this here:

This might be the case that you have to change the text manually in the mobile CSS (above)
Or you can try to use the LAytheme Text Formats:

On the bottom you can see Phone Font Size.
Good luck!
