I would try 8... e5 instead, accomplishing your idea of putting the pawns on dark squares, followed by f6, Kf8 and Ke7. If the white king comes to g6, you just move back to f8. The knight will always have a move that the bishop doesn't cover. The most challenging idea looks like playing h4 and g5. For example:</p>
  
  <pre><code>[White "Villain (2200)"]

  </code></pre>
  
  <p>and it doesn't look to me like White can make progress. If White brings the king to support the g-pawn instead advancing the h-pawn, Black could recapture on f6 with the king and that also looks like a fortress.</p>

  <p>Admittedly, earlier in your line, White could aim for a passed h-pawn instead of exchanging with g4. And 8.d5?! doesn't look very smart either. But the position should be drawn anyway.</p>
  
  <p>Anyway, this "second plan" looks like the most natural: ask white to demonstrate how he plans to makes progress, exchanges pawns and block the passer on a dark square.</p>

  I think it is good to notice the possibility of different fortresses, like the one you mention, and of course the wrong coloured bishop for the h-pawn. But to turn reaching such a fortress into a "plan" is way to early in this position.
  
  I think fxg3 was probably ok. At the first glance it looks ugly that now there are white prospects for a passer on the d-line and on the h-line, but your g and f-pawns can actually deal with the white g and h-pawns. Against g4 and h5 you should play f6 and against h4 and g5 (like in the game) you could have played g6. These setups prevent an h-passer.
  
  But maybe 10.f6 was still ok. Then you certainly should have played 11…fg 12.Kg5 Nf8 which prevents the intrusion of the white king. But even here h5-e4-e5-h6 and Kf6 might just win for white.
  
  An engine will be able to come up with better lines, but my feeling is that
  
  * Keeping your pawns compact.
  * Keeping the white king away.
  * Preventing a h-passer.
  
  might have earned you a draw. (Coincidentally you violate all these guidelines with the move e5, after which you are surely completely lost.)

  What if you don't play `fxg3`? It seems that white `h-pawn` and `g-pawn` that can create a passer is a big head-ache for black. It does not look like white can capture `h-pawn` easily, their doubled pawns on the `h-file` would not look very good.

  Admittedly, earlier in your line, White could aim for a passed h-pawn instead of exchanging with g4. And 8.d5?! doesn't look very smart either. But the position should be drawn anyway.
  Anyway, this "second plan" looks like the most natural: ask white to demonstrate how he plans to makes progress, exchanges pawns and block the passer on a dark square.

  I know I am late to the party, and it should be a draw, but none of the answers really hit on the easiest plan, and that was f5, making is impossible for white to create a passed pawn, except for an h-pawn, but the white bishop cannot control the queening square.
  The structure is similar in reasoning to the question I posted here.
  f5 looks weakening, but the only weakness, e6, is easily defended by the black king, and the white king does not have time to run to d7 to help the bishop attack it, or the black knight will wreak havoc.

  Against a human it could certainly happen. Black should not resign!
  But against a computer maybe, my intuition say no.
  
  More importantly is how good are white and black at endgames. That could be worth more than a pawn.
  
  I would play on as white and expect to win. But I always expect to win endgames:)
  
  I would play on as black and expect to draw. But I am confident in my endgame play.
