How do i separate the playback of the two tracks?
Like I said, either 1. pan them differently (pan one to the left, one to the right) or 2. shift one in time a
lot. Either of those changes will largely eliminate the phasing sound.
You
might also hear some improvement by rolling off the high frequencies on one of the two tracks, since this is where the phasing will probably be most noticeable if you nudged the track only slightly. That said, it's probably better to just pan one hard to the left and one hard to the right.

There will always be some cancellation when you mix
any two tracks, even if the signals are completely unrelated. However, it occurs in such small amounts that your ear won't perceive it as cancellation. You'll just hear it as the natural blending of two sounds.
What you hear as a phasing sound is noticeable because the signals are
constantly just a little off from each other, and always in exactly the same way---every cycle is off by a fixed amount. That's why doubling tracks by recording two separate performances will always sound more believable than simply playing the same track twice or recording it with two mics. If you do two separate takes, you get subtle variations in wave shape and timing, so you don't get cancellation of the same parts of the signal in the same way in every cycle.
As for shifting it more, it will eliminate the problem, but you'll have to shift it a
LOT more. You have to make it so that the natural variations in the sound don't always hit at the same point in every cycle. With every cycle that you shift the second track, the differences between the two tracks at any point in time will increase. At some point, it will no longer sound like phasing, and will instead sound more like a fast echo.
