I would say you have to combine preventative pawn play on the queenside - perhaps with a knight manoeuvre that covers queenside squares, with a kingside attack...don't forget the rook lift Re8,e6 to g6 or h6 and possible piece sacrifices against white's kingside structure.
Queens gambit exchange variation.

I dug this up:

Something which black shouldn't usually play is ...h6 I have found.

In the website MervynS gave, white played Nf3, instead the absolute mainline nowadays is for white to play Bd3 then Nbd2, and later he can play f3, d4
This is much more dangerous I believe because white can combine both minority attack and center expansion, while the pawn on f3 instead of the knight takes away g4 square for black's bishop.
I used to play QGD, but nowadays because of this variation I switch to playing nimzo indian move order, and only play D5 when white commits to Nf3, if Nc3, then I go for nimzo.

I looked at some games, it seems that in the Nge2 Exchange mainline, black mostly just sit tight and defend, play moves like a6, try to trade some pieces, and hope that his pawn weakness isn't enough for white to win, which is often true.
Hi
In games with this pawn structer white has three planes
-qeenside castle and kings side attack
-play in the center
-minority attack
The first two it's simple what black is supposed to do.
But when white playes the minority attack it's not so clear what black should do i have seen games where black tries for a kingside attack but most of the times it dosent work and where black waits for white to get his pawns to his side and then improve his pawn structer.
My questions are how does black acomplish the seconde and how does white fight vs blacks plan
