Lyds19089, from what I gather, the main component of soy that carries the goitrogenic properties is the "isoflavones." Some products, like soy milk, soy flour, and soy protein powder retain a lot of those, so you are right to generally avoid the list of things you mentioned (like the soy pasta, which is made from soy flour I think).
In fact, the isoflavones are what some people think are so great for you, so packaging will brag in large type how much the product has - so it's often easy to spot!
The effect is lessened in fermenting, so a little tofu here and a dollop of soy sauce there isn't going to hurt you. And if you're eating mostly whole foods, the incidental amount of lecithin you'll eat is really no worry at all except for people with allergies. And there's no way I'm giving up my dark chocolate, either! (I'm hypothyroid too, btw.) You can get chocolate made without lecithin, but I don't bother.
Some cruciferous veggies have a similar goitrogenic effect, but cooking lessens it. I'm sure a lot of foods have an effect, maybe some we don't even know about, but thyroid medication is titrated to our bodies over time, so that should make up for it.
