Soy protein is complete, assuming you are using the World Health
Organization's definition of "complete". This is well known,
and efforts you may have seen to debunk this are rubbish.

Quinoa is also complete, but just barely. There are probably many
other complete single vegetable proteins but they are not
high-protein vegetables and so this aspect is not nutritionally
significant.
