The most popular newbie advice I’ve heard is “use WBTB”. I’m new myself, but I’ve tried WBTB and it just didn’t work for me. It threw off my sleep schedule for days and made me miserable, and no lucidity whatsoever. That said, i’ve heard a lot of success stories about, so you might want to give it a shot! If that’s the case, take a gander.
I can’t claim to be massively experienced, but I can see how MILD isn’t for everyone. I’ve found it to be relatively successful, but then you might well differ. From what I’ve heard, it takes a lot of patience. If you want some extra assistance on it, try here and here. WILD, like you’ve been trying, also seems to vary; for example, I find WILD to be completely ineffective on me, because I simply don’t seem to experience HI in any form. However, some people drop into lucid dreams like no tomorrow with it, and I read somewhere that it’s the “holy grail” of lucid dreaming once you get hold of it. But that’s the rub: maybe I would get HI, but I’m not because I’m doing WILD wrong. The general consensus on WILD that I’ve heard is that it’s very difficult. For some pointers, look here and here.
My personal favourite technique is chaining (I think its formal name is DEILD). I like it because it’s very easy and doesn’t disturb sleep much, if at all. It also has (for me and the people I’ve talked to at least) a relatively high success rate! My sole lucid dream so far came from chaining, and I’ve had at least one since (and probably more), but IRL interruptions have kept me from remembering them properly. You can find a full guide on it here, and a nice thread on it here.
CALD is another technique, and I must confess that it seems very strange to me. However, it’s not my place to judge; I’ve been told that some people find it works very well! I also know next to nothing about it, so for better explanations look here and here. Another one of the more obscure techniques is FILD. I hardly know anything about this, except that it’s a variant on WILD. Might be worth checking out.
The problem with recommending for this kind of thing is that it’s so massively different for everyone. I like MILD+chaining, but Bobby B down the road can’t stand MILD and is a WILD addict who experiments with CALD. All in all, an awful lot of the learning process is just trying out different techniques until you find one that works for you. Give 'em a shot, and sweet dreams!
