- Da li (+Subject if it is necessary, or cannot be inferred from the conjugation) + Verb ... Example: Da li Ivan živi u Novom Sadu? Da li živimo u Novom Sadu?

- Da li + se (+ S) + Verb in case of verbs with reflexive pronoun 'se' ... Example: Da li se on zove Ivan? Da li se budiš u pet ili u šest?
Let me add the word order commonly used in colloquial speech:
- Živi li Ivan u Novom Sadu ? - Verb + li + (S)
- Jesi li u Parizu ? - To be (only the full forms: jesam/jesi/jeste/jesmo/jeste/jesu) + li + (S) ...
- Zoveš li se Ivan ? - Verb + li + se + (S) / Jel' + se +(S) + Verb
Exercise: Make 6 Yes/No questions about Ivan. The answers are in the first comment, because Ivan doesn't feel like recording his own voice right now :o(
