If you’re looking for Seforim, the Mesilas Yesharim (available with an English translation at any Judaica store or online) is a great one to start with.
But as others have pointed out, this is a journey that can become difficult and confusing if attempted alone. Try reaching out to a local Orthodox Rabbi who will be able to guide you along, and who will be able to give advice tailor-fit for your specific situation.
In the interm, there are several great websites that can help you more about Orthodox Judaism, among them aish.com (especially their Judaism 101 section) jewishpathways.com.
May Hashem grant you much hatlocha on your path, and don’t hesitate to ask anything else here!
