In German, verbs can mean more than one thing. For example, the verb "haben" can mean: to have, and is having. So there is nothing that can be put in place of
-ing. As for -ed it makes a verb past tense in English, but in German there are many different types of past tense. There are also differences between weak and strong verbs. For example, the verb "laufen" means to walk. If you wanted to say "I walked" however it would be "Ich lief" or "Ich bin gelaufen". With other verbs, such as "entern" which means "to board (a ship)" you can say Ich enterne to say I board or I am boarding, but if you wanted to say I boarded you would say Ich enterte. There are always some other rules to know however, which require lots of studying in the language, and eventually you just know how to say verbs without even thinking about it.
