As far as the incident with Lorgar, I am pretty sure that the Emperor went to such lengths because he was concerned about the fate of humanity, and Lorgar himself. He was probably worried that Lorgar's faith could lead him down the path of Chaos, which it inevitably did. As far as making his presence known, he does. The Emperor supposedly personally ordered the construction of a space port on Cadia after the 1st Black Crusade. He also spoke with Alicia Dominica and the other Brides of the Emperor, which in turn made them turn of Goge Vandire, ending his Reign of Blood. A more recent occurence was when he spoke with Jaq Draco. Then there is the many instances of Living Saints, which heavily implies intervention on his part.
