The tiffcp command to convert a tiff file to tiled format would be
something like:

  tiffcp -t in.tif out.tif

However, there are multiple ways of handling pyramiding in TIFF format
and externally).  So you will need to be more specific about what you are trying
to achieve in this regard.  For instance, you could create GDAL style internal
overviews using the gdal_translate and gdaladdo commands.

 gdal_translate -co TILED=YES in.tif out.tif
 gdaladdo out.tif 2 4 8 16 32
