How do I process or examine each token consumed by the parser?

Override Parser.consume(). Put an class member action after the Parser class definition in your grammar file: 

class P extends Parser;
{
  public void consume() throws IOException {
    //do what you want with LA(1)
    super.consume(); // MAKE SURE TO PUT THIS IN!!!
    //do what you want with LA(1)
  }
}
