There is nothing to be sorry about.
Do you have any MXD which has the desired template? If yes, then open the MXD file > Remove all the layers from the Table of Contents. You should still see the Grids and Graticules in it since it is a property of the Data Frame. Save this MXD to the C:\Users\<UserName>\AppData\Roaming\ESRI\Desktop10.x\ArcMap\Templates.
Optional
If you also want to preserve the symbology of the layers, then you need to save the layers in Table of Contents as Layer Files (.lyr). Then you can import the symbology of the saved layer files to your layers.
I feel that I didn't understand your requirement properly.
Could you explain your requirement further with appropriate screenshots?
