You didn't state whether you already held a bachelor degree.
One of the more common ways to go into education is to obtain a BA or BS in a field your passionate about, say math, english, science, or a foreign language. In addition to your degree, you complete a minor education or obtain a teaching certification. Note that teaching certifications vary by state so if you plan to teach in brick and mortar classrooms then you'll need to find out what certification your state of residence requires.
At the current time, math and science teachers, as well as special ed teachers (as suggested by other posts in this thread) do pay better than the arts and humanities, especially in many K-12 programs.
There are excellent online programs that will allow you to attain your bachelors in 2-4 years.
