Techno is kinda a huge genre, so to say you want to produce it is a bit general. What type of techno you wanna make? Detroit / Minimal / Euro / Acid /Gabba etc.
As far as I'm concerned Techno is Detroit and Detroit is Techno. Most other 4 beat dance tracks, (house / electro / tech house etc) have their roots buried in Techno.
When I was out at clubs all the time, you could hear a brand new techno track with some clever drop in, or strange hat pattern. And then 2 months later it was out there in the commercial world from the likes of Underworld or Orbital / Chem Bros etc.

But whatever you think of, "Techno Techno Techno" type techno, the original format is, in my opinion, the best genre of dance music to produce. Because as Mr ModnaR says, you should really just do what feels right to you, and you gets tons of freedom with techno. Lots of famous people have produced Ambient and passed it off as Techno, Dave Clarke, Oliver Ho, Kraftwerk of course and many more.
Listen to tons of techno and thats what you'll produce. There is no one formula that you can use, get out in the clubs. Try to screw it up and put 4 beats to it! I actually find using 2/2 time sig instead of the 4/4 gives you that militant euro stomp, if you want that.
Techno should sound like something repressed trying to escape - one of the old Detroit boys said that. Maybe Mad Mike.
But my final advice is, if you dont know where to begin, start with the detroit lot, you cant go wrong.
