Although both Golden Age and Galleon can be decidedly tricky terms to nail down in terms of specifics, there are a few books that cover the construction and handling of Habsburg Spain's ships. The relevant chapters of Pablo E. Perez-Mallaina's Spain's Men of the Sea: Daily Life on the Indies Fleets in the Sixteenth Century should be of use. Six Galleons for the King of Spain: Imperial Defense in the Early Seventeenth Century examines the construction of, well, six galleons for the Spanish crown in the 1620s. The long-term rebirth and eventual failure of Spanish naval power post-1588 is ably covered in the monograph Spanish Naval Power, 1589–1665: Reconstruction and Defeat by David Goodman which examines how the Spanish crown tried and failed to create a modern naval power.

Hopefully this helps.
