So: blinds, then deal 2 cards, then bet, then optionally hit/stand/etc around the table, then a final round of betting, then showdown?
It's blackjack, not poker, although it can be played 10-handed on a poker table.
Every player posts an identical 'blind' bet (players can optionally post for and play more than one hand). Nobody knows what anybody has until showdown.
Hole cards are dealt down, and first action is determined by button location (which is last to act). Each player can stand or hit (with up- or down-cards, see below) as they deem appropriate for their hole cards. Play moves around the table and concludes after the button player acts.
Hole cards are then revealed (typically in action order), best/winning hand(s) identified, and pot awarded accordingly.
It varies by house rules, but usually a true 'blackjack' hand beats a 21 using 3+ cards. It's also up to your house rules how many (if any) hole cards are dealt face-up (I prefer none), whether subsequent 'hit' cards are dealt face-up or down (I prefer down, so busts are hidden until showdown), and whether or not splits or double-downs are allowed (I like allowing blind splits for posting an extra bet, and being able to expose your down cards equalling 11 for no extra bet and getting a single down card, if using the alternate payout rules below).
You can also implement alternate pay-out rules, such as:
-- 3/4 pot to best hand, 1/4 pot to 2nd best hand, blackjack scoops (unless beaten by below)
-- a double-down 11 that hits 21 beats a blackjack
