But seriously, what you're describing might be partially cauesd by proximity effect from being just a little too close to the mic and/or deemphasis of the upper harmonics caused by holding the mic too low. While you can kind-of compensate with EQ (bump up the formant regions a little), it's probably better to redo the recording with better mic positioning. Experiment with distance from the mic, mic height, etc. until you get the character you're looking for.
That said, if you do decide to fix it with EQ, try doing a bump around the upper formant regions. The exact frequency varies from person to person, but for a good guess, check out:
