I'm not too sure, I've only just started working on my voice recently myself! I know from a couple of voice therapy sessions that you should 'lift' your adams apple, as if you were about to swallow, and if you then try to hold the expression you have when you're about to laugh then you can raise the pitch a little. Also change the tone on words more often, with intonation at the end of sentences; guys talk in a more monotonous voice 
Pretty much this, especially trying to lift your Adam's apple. Also, the main goal with the Adam's apple thing is to make your voice resonate in your head instead of in your chest. Holding one hand against your chest and the other against your cheek/jaw might help you adjust this, since you'll feel vibrations where your voice resonates.
Also, remember that male and female voices overlap in pitch. My voice is still kind of deep, but my sister's voice is deeper, and one of my female cousins has an even deeper voice. I've probably raised my voice around half an octave, but I also avoid bringing it too far up; in general, it's common for women to start and end conversations in a higher pitch, and I've found that leaving enough room pitch-wise to do that helps as "camouflage", since it's a common female speech pattern. Even though my voice is still lower than I'd like and more monotonous than I'd like, it seems to pass even on the phone - but when on the phone with strangers, I take extra care to start the conversation in a very feminine, high-pitched voice, before I drop down to my regular pitch and "mode".
