Ciao Ronak, there is no easy way to do what you need to. The metadata encoding/decoding in the geotools geotiff plugin has been built having as a target imageio, thereforere once you put the relevant metadata together what you get is a tree that you can pass to an imageio writer. The writer is responsible to write that out as a geotiff header not geotools. As I said it is not going to be easy to replicate that funzionality alone.
