The forms, and the ones you will actually see
Take the infinitive stem and add -e, -est, -e, -en, -et, -en. In practice, the er/sie/es form is the one that appears in news, because it is the only one clearly different from the normal present for most verbs. The highlighted cells are the forms in real use.

Yellow: clearly Konjunktiv I and common. Grey: identical to the present, so replaced by Konjunktiv II (sie hätten, wir kämen) in careful writing.
Direct speech to reported speech
Three things change: the verb takes Konjunktiv I, the pronouns shift to the reporter’s point of view, and dass is optional. Without dass, keep main-clause word order. Choose a sentence type.
What changed: ich bin → sie sei: the pronoun shifts to the reporter’s view, and bin becomes sei.
Reporting past and future
Konjunktiv I has no simple past. For anything in the past, use habe or sei + participle, whatever tense the speaker used. For the future, use werde + infinitive.
A news report in Konjunktiv I
Konjunktiv I forms are in red. Notice how the reporter never states the claims as fact. Every word has its English meaning underneath.
In conversation: what people really say
