The above site is good, and provides lots of examples.
I also wrote the book Real Chip Design and Verification Using Verilog and VHDL, 2002 that addresses techniques for logic designs, including the design of a CPU using both FSMs and microcode.
See http://systemverilog.us/RealChipDesign_preface.pdf for the table of contents.
Since it was written in 2002, it addresses Verilog, but that does not change the design approaches.
